Members of their Virginia Beach-based unit have said the men died after being sent to the bottom of the Super Pond underwater weapons-testing facility.

Senior Chief Navy Diver David Jones was among five men the Navy sought to punish for their roles in the accident. Jones originally wanted to have a court-martial instead of accepting the non-judicial punishment.

Jones’ court-martial charge of dereliction of duty has since been withdrawn.

Prosecutors rested their case against another diver facing the same charge in a court-martial on Thursday.
